Incensed by the decision, Chiellini referred to last season's controversial quarter-final between Madrid and Bayern, who lost 4-2 at the Bernabeu and 6-3 on aggregate after Ronaldo's extra-time victor came from an offside position, while Arturo Vidal was sent off.

The goal was enough to give the two-time defending champion a 4-3 aggregate win and avoid nerve-racking extra time after the Italian side had erased a seemingly insurmountable deficit from the first leg.

Referee Michael Oliver found himself in a sea of yellow shirts and sent Gianluigi Buffon off before the spot kick was even taken by Ronaldo, who converted it, of course.

In a wide open start to the game, Isco had the ball in the back of Juventus' net, but the flag was up for offside as he followed up after Buffon spilled Ronaldo's shot.

While Juventus players raged at the awarding of the penalty, Marca's front page simply reads "It was a penalty!", with a picture of Medhi Benatia appearing to push Lucas Vazquez from behind.

"At halftime I told them things had to change and we couldn't continue like this". Only European champions Real Madrid can better Bayern's tally of 11 semi-final appearances in the Champions League.
